iOS的Cookie管理

Posted on | | Views:

背景

最近有一个需求，需要手动的去缓存cookie，然后启动APP的时候设置缓存过的cookie，项目网络框架用的是Afnetworking。

解决方案

翻了下Afnetworking的issue，发现了作者对于cookie的解释

Afnetworking没有对Cookie做过处理

使用NSHTTPCookieStorage即可实现cookie的管理。上代码！

NSArray *cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookiesForURL:[NSURL URLWithString:url]];
NSData *data = [NSKeyedArchiver archivedDataWithRootObject:cookies];
NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
[userDefaults setObject:data forKey:@"cookie"];

NSData *cookiesdata = [[NSUserDefaults standardUserDefaults] objectForKey:@"m3cookie"];
    if([cookiesdata length]) {
        NSArray *cookies = [NSKeyedUnarchiver unarchiveObjectWithData:cookiesdata];
        NSHTTPCookie *cookie;
        for (cookie in cookies) {
            [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie];
        }
    }

}
